GNOME Bugzilla – Bug 637565
libgio-2.0-0.dll is not compatible with Windows 2000
Last modified: 2018-05-24 12:55:53 UTC
Hi, On http://www.gtk.org/download-windows.html the following is stated: "The current GTK+ stack uses APIs that are available only on Windows 2000 or later." A bit further on that page a download link is provided for GLib 2.26.0: http://ftp.gnome.org/pub/gnome/binaries/win32/glib/2.26/glib_2.26.0-2_win32.zip However, the libgio-2.0-0.dll from that zip uses the freeaddrinfo() function that is only available starting with windows xp [1]. Luckily, on [1] we learn that there's a workaround for earlier versions of windows in the form of wspiapi.h. Sadly, wspiapi.h is not freely available for MinGW (the one from http://mingw.org). There seems to be a copy from the mingw64 project (but it looks like it's provenance is under suspicion [2]). So, is this a bug in the documentation in that Windows 2000 is no longer supported for the official windows binaries? Or is this a bug with how the official 32bit windows binaries are built that can be fixed? Reproducing: - on a windows 2000 system - download and extract [3] to C:\gtk+-bundle\ - cd C:\gtk+-bundle\bin\ - gtk-demo.exe Result: A messagebox with the following error appears: "The procedure entry point freeaddrinfo could not be located in the dynamic link library WS2_32.dll" Thanks, Dieter [1] http://msdn.microsoft.com/en-us/library/ms737931%28v=vs.85%29.aspx, especially the "Support for freeaddrinfo on earlier versions of Windows" section. [2] http://permalink.gmane.org/gmane.comp.gnu.mingw.user/34741 [3] http://ftp.gnome.org/pub/GNOME/binaries/win32/gtk+/2.22/gtk+-bundle_2.22.0-20101016_win32.zip
actually, this should be win32, not network I don't know if Windows 2000 is still intended to be supported.
There is trouble in keeping GLib/Gtk+ useable on still relevant versions of Windows. I suggeest to not waste time on obsolete versions and just let the website state winxp sp3 or later. See bug #604458 and bug #603527 for more information.
Agreed. How do we go about this? Is a patch against gtk-web enough or is there more documentation that needs to be updated? Do we need to convince anyone (GLib/GTK+ maintainers) before actually writing said documentation patches?
A patch for the gtk-web/ module would indeed be enough. Though it might be nice to spell out the Windows requirements in the glib reference docs too.
Created attachment 253587 [details] [review] make gio 2.36.3 work on Windows 2000
Why give up W2K compatibility so easily? The attached simple patch against 2.36.3 makes gio work again under W2K, at least when crosscompiled using mingw-w64 (because mingw-w64 ships wspiapi.h, which contains the freeaddrinfo emulation routines that are used if the native routines are absent, i.e. on W2K).
